Race the Sun serves up enough adventure to challenge those looking to lay down a fast time, as well as those who just want a fun, exhilarating day with friends and family.

Teams of 4

It's achievable by people with a reasonable fitness level who are prepared to train beforehand. The more you train, the more you’ll enjoy it.

Some teams will complete the challenge in as little as five hours and others will take the whole day. Some teams want to compete for the fastest time and others want to simply complete the course – it’s really up to you!

It’s a great incentive to get fit and work different muscles, knowing you’re raising funds for an excellent cause at the same time.

Bike type

Road, hybrid or e-bike.

As the route is on-road, using a mountain bike is not recommended. However, if you have trained on it and are confident you can complete the course you are more than welcome to use it. 

You will provide your own bike which should be in good working order. Getting your bike serviced before the event is recommended.

On-site bike mechanics will be available at registration on Friday evening, and throughout the event to help with mechanical issues encountered on the event.

E-bikes

In the interests of fairness using an e-bike means the entire team will not be eligible for any of the ‘fastest team’ award categories.

Please ensure to carry spare batteries, or other spares specific to e-bikes, as these may not be available from the bike mechanics.

Fancy dress award

There is a Best Dressed Team Award for those who want to go the extra mile! It's about having fun and raising money for charity.

Spectators

Why not make a weekend of it with friends and family?! Supporters will be able to join you at the event HQ, then track your progress live online.

Stage 1 - bike

Your challenge begins on the rolling clifftop roads and countryside of East Sussex. 

This circular bike route delivers epic sea views, quiet lanes, and a few cheeky climbs to keep things interesting—an exhilarating ride to power up your Race The Sun experience.

Stage 2 - hike

Lace up your boots for a stunning coastal adventure!

Begin at Seaford Head, which offers up an Instagram-worthy view of the iconic Seven Sisters cliffs stretching into the distance as far as Beachy Head, before the route winds inland along the river to the tranquil curves of Cuckmere Meanders. Here, the adventure shifts gears as boots are swapped for boats for the paddle phase of the challenge.

After your paddle, rejoin the trail to conquer a scenic stretch of the South Downs Way National Trail. This section might be short, but it’s big on wow-factor—think sweeping landscapes and a glimpse of the striking Litlington White Horse, before looping back to base in Seaford.

image

Stage 3 - paddle

Your challenge moves onto an unforgettable waterside experience with a 2-mile paddle on the peaceful, non-tidal River Cuckmere. This section amps up the adventure and the teamwork as you navigate the course in stable sit-on-top kayaks. 

No experience? No problem. All gear is provided, and expert instructors are on hand to guide you every stroke of the way.

Celebration

After completing all three challenges, it's time to kick back and chill out with teammates, friends, and family. Enjoy a bite to eat and a drink on us as you celebrate your achievement and relive the highlights of the day!

RACE FOR A REASON
Race for children like Jack

Jack was born extremely prematurely at 25 weeks, weighing just 1lb 15oz.

He needed oxygen, help with his breathing and feeding tubes to survive. He suffered a collapsed lung and brain bleeds and contracted the potentially deadly bowel infection necrotising enterocolitis. Jack went on to endure many more serious health problems and spent four and a half months in hospital fighting to survive before he was finally allowed home. Jack's mum is so grateful for the work that Action does:

It is so important that studies like those funded by Action Medical Research are done. Without research, we wouldn’t have medical advances, and Jack probably wouldn’t be here.

Very well organised event, beautiful scenery, cracking day, friendly and helpful staff. Thoroughly recommended. Andrew K

The event was incredible and we were all really impressed how well it was all organised. The food provided before, during and after the race was amazing. The signage around the course was great. The logistics on the day and the communication leading up to the event was perfect. Matthew B

We had a fantastic weekend, and loved the novelty of doing 3 different disciplines. What took the event from being really good to being really special was the atmosphere created by the Action staff and the other participants who were all incredible! Finisher

Really helpful staff, never made to feel silly. The fact that a medal and drink and bbq are included was really fantastic. Anna G

A great day out, and the weather was kind. Hard work, but the cycle wasn't as bad as I thought it would be πŸ‘. Would recommend it, but make sure the legs can walk up big hills!! Ruth B
